IMPROVEMENT lN REVERSE-WAY cocKs.

Specification forming part of Letters Patent No. 205,209, dated June 25,1878; application filed March 27, 1878.

To all whom it may concern:

Be it known that I, ELIAS B. QUICK, of the city of Brooklyn, Kingscounty, New York, have made a new and useful Improvement in Reverse-WayCocks; and I do hereby declare that the following is afull, clear, andexact description thereof, reference being had to the accompanyingdrawings, making apart of this specification.

The object of this invention is to provide simple means of governing andreversing the flow of liquids through vessels, such as filters, chemicalapparatus, and the like, and of establishing the flow throughservice-pipes past such vessel, filter, or apparatus at the will of theoperator.

Figure I is an elevation of my reverse-way cock. Fig. II is a plan; Fig.III, a horizontal sectional plan; Fig. IV, a sectional elevation; Fig.V, a sectional plan. Figs. VI, VII, and VIII are sections similar toFigs. III, IV, and V, showing the parts in different relative positions.

A is the shell, fitted to receive the plug B. Upon the shell A are fourbranches, or, b, d, and 61. The branch d terminates in the shell A as aport, to match the ports f andg in the plug B. The branches at and I)also terminate in the shell A as ports, to match a series of five ports,h, 6, 7c, and l, in the plug B. The

, branch d is at so great a longitudinal distance from the branches orand b that the two series of ports in the plug B do not overlap eachother.

The lower series of ports 71, t', j, k, and Zin the plug B are spaced atequal circumferential distances from each other, so that one-fifth of arevolution of the plug B will bring the next succeeding port oppositeeither given port of the branch at or b. The ports of a and I) do notopen into the shell A upon a diametric line, but are so far removed fromit that when one of the five ports in the series h t j 70 Z matches aanother will match b, as seen in Fig. V, where 1 matches a and 1'matches I). The port f is in line with the port h and the port 9 is inline with the port I. The plug B is closed atboth ends; buttheclosing-diaphragm at the smaller end is flexed upward or in ward, so asto make the ports 2' and it open through the Walls of the plug below orexternally to the hollow body of the plug B, while all the other ports,h, j, I), f, and g, open into the common hollow body of the plug B.

The above-described flexure of the diaphragm forms the channel 0, whichis always open to the branch d.

the branch dis similarly connected to another compartment, and thatthere is filtering or chemical material between these compartments,through which it is desired to cause a flow of liquid by virtue of apreponderance of pressure existing in a.

If the plug B be placed as shown in Figs. III, IV, and V, the fluid willpass into the body of the plug B through a and b, and into d through f,and enter one compartment, pass through the filtering or chemicalmaterial to the opposite compartments, thence to the branch d, thencethrough the channel 0, port t, and out through the branch I). If theplug B .be now turned one-fifth of a revolution to the position shown inFigs. VI, VII, and VIII, the liquid will flow through It and c to d, andpass through the compartments and filtering or chemical material in theopposite direction to that before described, and pass out through d g,h, and b. If the plug be again turned one-fifth of a revolution in thesame direction A as before, the ports h and is will match the ports of aand b, and all the other ports will be closed, so that the liquid willpass directly from ato b through the hollow body of the plug B. If theplug B be turned one-tenth of a revolution from any of the positionsabove indicated, none of the plug-ports will match a shell-port and theflow of liquid will be arrested.

It will be observed that the ports of a and b open into the shell extradiametricallythat is to say, aside from any diameter passing through theaxis, and so far aside as to make the ports of a and 12 match orcoincide with ports in the plug spaced one-fifth of a circumferenceapart, from middle to middle, and, again, so far aside as to give theports of a and]; the appearance of being closedin those 2. Thecombination of the shell A, having figures which are Sections upon theaxis of the four branches'a, b, d, and d, with theplug the shell andplug, while the cross-sections B, having the channel 0 and ports f, g,h, i, j, through the branches a, b, and d show clearly k, and 1,arranged substantially in the manner the construction of the parts. andfor the purposes described.
